Would be interested to know why bundler cache hasn't been enabled on Travis. Thank you.
**Describe the bug** ruby-graphviz seems to generate invalid dot formatted numbers for bounding boxes of 6 digits or more. This may be an issue with how all numbers get formatted...
@glejeune - This may be a ruby 2.4 idiosynracy, I didn't take the time to diagnose it further. Essentially, sometimes the status returned from output_and_errors_from_command is nil, which does not...
